I'm wondering if any of you might be able to help answer a question?

This 1970 I bought has a sag in the DS front suspension. I have changed the coil springs, and shocks, but the DS still sits about 2" lower than the PS.
Make no sense why it is still doing this.
Doesn't appear to be bent, but I am concerned about tire hits on the DS fender. Any clue why this is doing this? Or any idea how to solve the problem without using Bubba knuckle busters to spread the new coil!!

Thanks again to all.

Maybe body mounts???

could be that the one spring is not seated correctly?

They're in there right. This is the reason I switched the coils to begin with, and while it isn't as bad, the DS droop is still there.

Check your rear suspension. Something that is off on your rear, i.e. spring, could adversly affect your front.

I second the body mounts

How does the car track when driving?

What are the number and thickness of the front end alignment shims?

Are there a large number of shims under the hood supports (hinges)?

Have you checked the frame dimensions against the values in your GM shop manual for the 1970?

sounds kind of scary to me. 1970 should be solid mounted, i.e. steel shims rather than rubber cushions on the body.
i think the starting point is determining if the body is sitting on the frame fowl-eyed or if the frame is not parallel to the ground. this should be pretty easy to check simply by using a tape measure or ruler at various points between the body/frame/ground. if the body is sitting evenly on the frame, it's probably suspension related. some kind of damaged bushing or bent arm or the like.
if the frame is not parallel to the ground, it could still be suspension but also may bring up the possibility of frame damage.
if the body doesn't sit evenly on the frame AND the frame isn't parallel to the ground, certainly sounds like possible frame damage.
now i'm going to ask a really stupid question.... are the front and rear pairs the same size?

VegasJen

yet another interesting software edit. so i can't say fowl-eyed. i suppose i also couldn't say i cocked the hammer on my revolver. oh well, all in the name of not offending anyone. :rolleyes:
but if i want, i can type azz, $h** (i could make it really obvious but not interested in loosing points to make a point) or, well, you get the picture.

interesting, i can say cocked but not fowl. :confused:

I wonder if there are any guy's named Dick who are members of the Forum????

BTW I agree with your advice on garandfan's problem.....

I think Dick-eyed is the operative word........

I just thought that maybe you have to capitalize it fowl-eyed........


No.....they've covered all the bases....... :lol: Dick-eyed will have to do..........

Mine did the same thing - sat lower on the DS. I got under the car, and noticed I had some frame damage. You may or may not have any, and it may or may not be obvious - just another thing to check. See this link for pics - http://forums.corvetteforum.com/zerothread?id=590922 :smash:

Ditto WPE. Look for rips in the front cross member and broken welds at the lower A arm/crossmember location.

Has the car been in a wreck?

Did you put new coil springs in or used? Did they seat right up top as well as the bottom.

Did you put new a-arm bushings in? If so, did you tighten the end bolts before you installed them?

Just a couple ideas to throw at you.

Thanks Guys

I'll lift it up again tomorrow, and check the front frame. I looked once and saw no damage.

As far as it ever being wrecked, I don't know, might have been.

Car turns, and drives true. No steering wheel play, and you can take your hands off without having it steer out

Tires are 225/70/15 both front and rear.

Coils are new stock 350/350 non/ac coils.

I'll let you know if I find any damage.

Thanks again, Frank

Checked the frame, and upper and lower a-arms. No damage that I can see.

PS frame height sits 1/4 inch higher than DS, Not enough to cause this much listing.

I wonder if it could be the a-arm bushings? They are checked, but not completely gone. (this is my winter project)

goofygrin

someone mentioned it earlier, and i seem to recall it was a problem for someone else, but check the rear too. seems like if one side was off (spring broken, out of alignment) that it would affect the opposite corner in the front...
